Twenty-five barrows (initial BW = 8.53 kg ± 1.48 kg) were used to determine the apparent (AID) and standardized (SID) ileal AA digestibilities in micronized full fat soybean (MFFS) with or without multi-carbohydrase (Carb) and phytase (Phy) enzyme supplementation. Pigs were allotted in a completely randomized design under 5 treatments and 5 replicates. The experimental diets consisted of MFFS as the sole source of protein without enzymes, with Carb, Phy or Carb+Phy. A low-protein diet (5% casein) was used only to calculate the digestibility of the MFFS. All diets contained Chromium (0.3%) as indigestible marker. Pigs were given their daily feed allowance at a rate of 4.5% of BW determined at the beginning of each experimental period. Animals were slaughtered at d 43 and ileal contents collected. The data were analyzed using the GLM (SAS Inst. Inc., Cary, NC), and means were compared by Tukey’s test. The AID and SID of AA in MFFS (without enzymes) were lower (average 16.9 and 14.7%, respectively) compared with NRC (2012). Underestimated digestibility coefficients may be related with animal ages in the present study, since most of the studies related in literature were obtained from pigs with higher weights. There was no effect of Carb, Phy or Carb+Phy (P > 0.05) on AA digestibility. According with literature, sometimes the use of exogenous enzymes to degrade indigestible dietary components has inconsistent results mainly because of the presence of complex substrates in feedstuffs and the use of enzyme activities often not suitable for effective hydrolysis of such components. The AID and SID of AA in MFFS (without enzymes) were, respectively: Arg, 71.6 and 76.5; His, 69.8 and 77.0; Ile, 59.9 and 66.0; Leu, 68.1 and 74.2; Lys, 75.8 and 79.6; Met, 72.3 and 81.1; Phe, 68.8 and 74.2; Thr, 61.4 and 74.6; Val, 65.2 and 72.1; Ala, 66.7 and 78.0; Asp, 66.9 and 69.8; Glu, 71.1 and 75.0; Pro, 70.1 and 80.7; Ser, 70.0 and 81.5; Tyr, 68.9 and 74.0. Carbohydrase and phytase, alone or in combination, don't affect AA digestibilities of MFFS for weaned pigs.
